A monolayer of cells on a blood smear is best described as:

A monolayer of cells on a blood smear is best described as:

• A. Feathered edge
• B. Cells with no overlapping or touching
• C. Cells touching each other very closely with some overlapping
• D. The body of the blood smear

Answer: (B)

The key idea is that a monolayer is a single, thin layer of cells lying in one plane so each cell can be seen clearly without stacking. In a properly prepared blood smear, this region has cells that are spread out with minimal or no overlapping, allowing accurate assessment of each cell’s size, shape, and features. That’s why the best description is cells with no overlapping or touching. The feathered edge refers to the wispy outer part of the smear, where cells are dispersed more loosely. The body of the smear is the thicker central area where cells can stack and overlap, making it harder to evaluate individual cells. So a true monolayer corresponds to a single-layer arrangement without touching or overlapping cells.
